CONRAD FRANZ, OF ERIE, PENNSYLVANIA, ASSIGNOR TO GERMER STOVE-CO1VIIPANY,

OF ERIE, PENNSYLVANIA, A CORPORATIONOF PENNSYLVANIA.

HOT-PLATE.

Be itknown that I, CONRAD zen of the United States, residing at Erie,

in the county of Erie and State of Penn sylvania, have invented new and useful Improvements in Hot-Plates, of which the following is a specification. v

This invention relates to hot plates and consists in certain improvements in the con struction thereof aswill be hereinafter fully.

described and pointed out in the claims.

It is desirable to provide the burners of 1 hot plates with protecting rings to protect the burners from drafts.

The object of this invention is to simplify I the method of-supporting these rings.

The invention is illustratedfinthe accompanying drawings. as follows x j Figure 1 shows a plan view of a part of a hot plate extending over the burner. Fig. 2 a section on the line 22 in Fig. 1. Fig. 3 a section on the line 33 in Fig. 1. 'Fig. 4 a section on the line 4+4 in Fig. 2. Fig. 5 a

with the grate removed. 1 marks the plate frame, 2 the top'plate of the hot plate, 3 an annular lip for supporting grate, the lip being slightly de-,

pressed from the surface of the plate 2 so that the surface of the grate may be flush with the plate.

4 marks the grate; the lip 5 at one side which books. under the edge of the plate 2 and issecured at the opposite side by the bolt 5 which extends through. the lip 3. Two pockets 6 are 'ar'-. ranged in the lip 3. These are simply depressions in the lip and the arms extending from the protecting ring 8 pro ect into these pockets, thev pockets being deep enough to receive the arms 7 with the grate in place. The burner Qjh'as-the mixing tube ,13 extending laterally from it and is provided at the side opposite the mixing tube with a projecting lug 10having a pin projection 11 which extends through a lug 12 extending inwardly from the ring 8. This connection through the lugslO and 12 forms Specification of Letters Patent.

plate 16. The mixer plate 16 has an angle 18 at the top secured to the top plate by a bolt 19. The part 14 of the mixer is supplemented by the mixer ring 20 on the outside of theplate 16 and thevalve connection 21 extends to the gas pipe 22. In order to maintaln the burner'in. a horizontal position the ring 15 is provided witha small key lug 23 which extends into a slot 24 in the part 14 of the mixer.

It will be observed that when these parts are assembled the protecting ring 8 is supopposite side of this ring rests on the mixing. tube 13 and the burner is supported by the connection formed by the lugs 10 and 12 and-bythe mixing'tube which extends into the ring 15. The result is that while these parts. can'be readily assembled and readily detached when desired they are so interlooked that they form a' comparatively rigid structure when in use so that when'lthe hot plate is moved from place to place there is no disturbance of the relation between the burner and protecting ring. At the same time the assembling of these parts is very simple yet very efiicient.

What I claim as new is 1. In a hot plate, the combination of a top plate; a burner below the top plate; a mixer tube extending laterally from the-burner; a protecting ring around the burner supported on one side on the-mixer tube and at the opposite side by the top plate; a connection between the burner and the protecting ring at the side opposite the mixer tube; and

means for supporting the mixer tube outside the protecting ring. I v
